Free one-to-one web meetings

I'm on a roll with free things today.  The Distant Librarian alerted me to ASAP Express from ConVoq, a free "full featured personal online meeting solution."  You can get the one-to-one meeting application for free.  It includes a nice real-time "Am I available" link that lets people know if you're at your desk or not, supports various IM products, VOIP, video, file transfers, PPT, and screen sharing (!).  I haven't tried this out yet, but am interested to hear from folks who have.
